I'm trying to move to 4.9 from 4.8. It's a fresh install on a different disk. I've copied over all the old network config files and pf.conf and am using them. I've edited the wireless's hostname.ral0 file to account for the syntax change. All the interfaces are the same (I'm swapping disks back and forth to get on the internet). Using the 4.9 disk I can ssh in from my internal network to the 4.9 firewall and from there ping, say, oracle.com. I can ping from the internal network too. But I cannot get incoming on port 80.

Nothing has changed anywhere except I'm using a 4.9 install for the firewall. There must be a 4.8 -> 4.9 gotcha, perhaps in pf, that's breaking internet. Can I not re-use config files from 4.8?
